BRICK-TRUCK.

' SPECIFICATION forming part of Letters Patent No. 740,629, dated October 6, 1903. Application filed May 20, 1902. Serial No. 108,184. iNo model.)

To all whom t may concern: Be it known that I, CARL A. CARLSON, a citizen of the United States, residing at Barberton, in the county -of Summit and State of Ohio, have linvented a certain new and useful Improvement in Cars for the Transportation of Brick in the Processof Manufacture, of

which the following is a specification.

My invention has relation to improvements in cars for the transportation of brick, sewerpipe, `and kindred articles during a certain stage of their manufacture.

l In the modern process of manufacturing' brick the green brick are stacked on wooden platforms which rest on supporting walls or benches on opposite sides of a car-track. The elevation of these platforms above the cartrack is such that a car with a verticallymovable truck-frame can freely pass under them when the frame is in its lowest position and which will be engaged and raised with their load when the frame is raised and then be thereby conveyed to and deposited in the dry-kiln on like side walls or benches and the car again withdrawn, and thence finally conveyed to the burning-kiln by a repetition of the process. 'During this stage of their manufacture it is of importance that not! only facility in moving the brick be secured, but

that the temporary introduction and removal of the articles be accomplished without shock, and it is especially desirable that these ends be secured by the simplest mechanism consistent with the aforesaid requirements.

The object of my invention is to produce a Vcar of the general class named that will fulfil the foregoing requirements, will be simple in construction, easily operated, and which will subserve the additional function of enabling the movement of thetrack-car to operate to raise or elevate the platform.

To the accomplishment of the aforesaid objects my invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter described, and then specifically pointed o ut in the claims, reference being had to the accompanying drawings, which form a part of this specication.

In the accompanying drawings, in which similarreference-numerals indicate like parts in the different figures, Figure l is a side elevation of a car embodyingrmy improvement, broken in the center both to shorten the figure and to illustrate4 the position of the parts when the truck-frame is in its highest and its lowest position; and Fig. 2, an end elevation in section at the line a: a; of Fig. l.

Referring to the figures, l is the car-frame,

having the bearings 2, in which are journaled On each side.

the axles 3 of the car-wheels 4. of the frame l, substantially centrally over the bearings 2, are secured like inclined ways 5, the lower ends of which are curved upward to form a stop for wheels 6, to be described, and the upper ends having a curved depression, preferably concentric with the wheels 6, to form a recess to hold them against slight ordinary shocks while the frame is in its elevated position. l

Above the car-frame 1 is a movable truckframe 7 of substantially the dimensions of the car-frame l and provided on each side, ver tically coincident with the ways 5, with bearings S, in which are severally j ournaled wheels 6, arranged to run on the ways 5. Y

In Aeach end of the frame lis a shaft l0, on the outer ends of which are mounted bell.- crank levers 1l, their upper ends being connected by links l2 with the frame 7. Hence it will be apparent that by elevating the free end'of the left lever ll or depressing the free end of the right lever the effect will be to draw the frame 7 toward the right of the carframe l, thus causing the wheels 6 to run up the inclined ways 5 until they rest in the depressions in their upper ends and as a result elevate the frame 7 and by the opposite move# ment to cause it to sink to its lowerposition.

The bell-crank levers 11 may have iiXed handles 13 or may be provided with sockets to receive detachable handles.

To retain the frame 7 in its elevated position, so as to prevent its return by gravitation or accidental cause, there is mounted on the shaft of the right wheels 6 a rocking bar 14, having its outer end suitably formed for the grasp of the hand and provided with a`hook to engage the pivotal shaft of the right bellcrank lever ll, and thus lock the frame 7 in place until it is desired to lower it, when the bar 14C is rocked upward. There may be one Patented October 6, 1903. M I

'ICO

of these bars 14, as shown in Fig. 2, but for convenience of reaching them readily from either side of the car and for greater security two bars will be found advantageous.

The brick are'placed on wooden platforms 15, that rest on opposite walls or benches 1G on opposite sides of the .car-track. lVhen it is desired to move them, the car, with its frame 7 in its lower position, is run under the platform 15 and the frame 7 raised by means of the levers 11 until the platform 15 is raised from the walls 1G and rests on the frame 7 and the car. In this operation the inclined ways 5 and Wheels 6 can be utilized to afford great assistance, as after the frame 7 has engaged the under part of the platform 15, so as to be sufficiently bound by friction against slipping thereon, the car be started to the left the effect will be to draw the Way 5 under the wheels,and thus practically compel the wheels to ascend them.

I do not intend by the foregoing description to limit my invention to the moving of brick simply, as it can be advantageously applied to movingsewer-pipe and other clay products, lumber, and other articles of a bulky nature or of great weight.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a car of the class specified, the combination with a car-frame having inclined ways, the lower ends of which are curved upward and the upper end's having curved depressions, of an upper truck-frame provided with Wheels arranged to run on said ways and rest in said depressions, substantially as shown and described.

2. The combination in a car of the class specified with a frame having inclined ways, and an upper truck-frame having wheels arranged to rest and. run on said inclined Ways,

of a locking device to connect said car and truck to prevent one moving separate from the other, substantially as shown and described.

3. In an elevating-truck, side beams having Wheels journaled thereon forming the running-gear of the truck, blocks secured to the upper side of said side beams each having an inclined upper face, an elevating-platform comprising a wheeled truck adapted to travel on said blocks, and means to act-nate said platform-truck, substantially as shown and described.

LI. In an elevating-truck, side beams having Wheels journaled thereon forming the running-gear of the truck, blocks secured to the upper side of said side beams each block having a rearwardly-extending inclined surface, an elevating platform comprising a wheeled truck adapted to travel on said blocks, and means to actuate said platformtruck, substantially as shown and described.

In testimony that I claim the above I hereunto set my hand inthe presence of two subscribing witnesses.

CARL YA. CARLSON.
